Potato Osmosis Lab

Good Essays
Most Organisms on earth have a process of water movement in their cell; in other words, they go through a process called osmosis. Osmosis is a form of diffusion in which water diffuses through a selectively permeable membrane from hypotonic concentration into hypertonic, or low to high concentration. For that reason, we set out to investigate a scientific question, which was to determent what the concentration of salt will be in potato. We used the information we gathered in class to find out if the different levels of salt concentration will affect water movement in the potato. In today’s lab, the main goal of the experiment will be to examine and observe the concentration of salt. The evidence gathered in this class stated that

However, if the concentration of the solution is smaller than, the potato cell, the potato cell will gain water because the solution will become hypotonic, meaning water will move from the beaker into the potato. In addition, if the potato’s weight remains the same after being soaked in the salt solution then the solution will be in the isotonic condition because osmosis does not occur in isotonic solution. Therefore, our assumption for this lab experiment is to detect if different salt concentration will reduce the osmosis movement in the potato while comparing it with pure water. Furthermore, if water moved into the potato the solution would be hypotonic which affects the potato’s weight meaning the concentration of the salt in the beaker will become low. If the potato loses weight, the solution will be called hypertonic or will have high concentration in the beaker. In this experiment we used four beakers, this beakers have a different salt solution, a solution with 0M (molar), 0.2M, 0.4M, and 0.6M by doing so we determined the concentration of salt in the potato and see which salt concentration solution make a change by gaining, losing or remain the same in the potato by measuring the water movement from one place…show more content…
Additionally, we examined how the potato reacts when we have a different concentration solution. Depend on this experiment our data determines that, if the amount of salt solution increases the osmosis movement in the potato will decrease, or the potatoes will loss weight which the result supports our hypothesis, but if the amount of the salt solution decreases the osmosis in the potato piece will increase or the potato will gain water. Our data and report showed that the hypothesis was right, and the result is as we expected, but if we added some independent variable for example if we change the salt solution to different solution we should see more result than we saw in this experiment. The result we get on this experiment supports our hypothesis because we find the reliable result as we learned in this class. However there are several factors that can cause our result, one of the factors that can cause our result could be when we measure our potato before and after can cause the result. Another factor that affect our result cloud be the salt solution concentration measurement may not be accurate that can affect our result as well as the first reason. For future improvement, we need to make sure that the size and the weight of the potatoes are equal, and the solution is accurate, and measuring the potato correctly before and after we soaked in the solution.
